If Paris is the capital of love, it’s no longer the capital of infidelity. According to Gleeden, it’s now Bordeaux that takes the top spot, with 13.26% of its adult population registered on the platform. This growth symbolizes a true change of era.
Close behind, Lille (12.94%) is right on its heels, while Paris rounds out the podium (10.44%). This shift illustrates the movement of practices and also the profiles: active individuals, often in relationships, with children, belonging to higher socio-professional categories. Far from the stereotype of marginal infidelity, these users lead well-established lives, where personal aspirations sometimes shake up the balance.

After the health crisis, a new map of desires
To understand this shift, we need to go back to the post-Covid period. The health crisis has deeply changed life priorities, prompting many French people to leave big cities for more breathable locations like Bordeaux, Lille, or Nantes.
With the rise of remote work, these new balances allow for a blend of career and quality of life… without necessarily changing romantic behaviors. Fewer constraints, more flexibility: the opportunities for parallel dating are multiplying.

This phenomenon primarily reveals contemporary tensions: between family life and the desire for personal fulfillment, between the stability we show and the longing for elsewhere. Infidelity appears less as a break and more as an adjustment.
Infidelity is now everywhere in France
Another key insight is that infidelity is no longer concentrated in just a few big cities. It is now spreading across the entire territory. Other cities in the rankings include Lyon (9.60%), Rennes (8.28%), Toulouse (7.77%), and even Nantes (7.27%). These are dynamic, attractive cities where lifestyles are starting to homogenize.

The digital world also plays a key role: dating platforms break down geographical borders and make these practices accessible everywhere. More than just a ranking, this study acts as a mirror to contemporary changes. It reflects a society in transformation, where life trajectories, couple dynamics, and individual aspirations are quietly reshaping.
